is this any way to get network location from mobile number .
There are few services that do it. But, because of privacy breach, the location is not too brief and is limited to city. For example, this website gives the info:

how much expense for it.
Even if you pay for it, AFAIK, it's illegal to share the exact location of the phone number. Only national security related and high profile teams can have that info.
So, even if you want to make such thing, it would be difficult as for this you need to have a tie-up with some provider and have to get a legal approval on the same.
